2 . through studying the effect of the dredging length , found that it is not a linear relationship between the dredging length and the relatively reduced deposition , for example when dredging exceed a certain length , though the relatively reduced deposition still increase slowly , the depositing volumes begin to decrease
挖槽长度对挖槽效果的影响的试验研究结果表明，河道相对减淤量的增加与挖河长度的增加并不成等比例线性关系，即挖河长度超过一定值后，虽然河道相对减淤量还有缓慢增加，但减淤效率开始减小。
